Description
Botryoidal clusters of rare Olmiite to over 2,5 cm on typical matrix from famous N´Chwaning II Mine of Kalahari Manganese Fields. They are showing beige colour, fine silky luster and so far I can see, the display face is pristine. Nice material from the 1990s as this stuff was discovered and at first mislabeled as Poldervaartite.
